杨树用材林主伐合理年伐量的测算——以安庆市迎江区新洲乡为例

Measurement on the Final Felling Rational Annual Cut of Poplar Timber Forests——A Case Study of Xinzhou Township in Yingjiang District, Anqing City

本文通过对安庆市迎江区新洲乡杨树用材林龄组、龄级的比较分析,对其主伐合理年伐量进行测算。结果表明,利用平均生长量法计算出新洲乡杨树用材林年伐蓄积量(8 802 m3)、面积(82.9 hm2),并初步测算出新洲乡杨树用材林主伐年龄为12年,按伐后1年更新,其轮伐期为13年,均满足安徽省杨树用材林理论上规定要求的主伐年龄及轮伐期。

In this paper, in order to measure the final felling rational annual cut, a comparative analysis was made on the age groups and age classes of the poplar timber forests in Xinzhou Township, Yingjiang District, Anqing City. The results showed that, with the method of the mean annual increment, the annual cut volume was measured as 8 802 m^3 and the area is 82.9 hm^2;The final felling age was 12 as preliminarily measured, and the felling cycle is 13 years with regeneration a year after the final felling,meeting both the theoretically required final felling age and felling cycle of poplar timber forests in Anhui Province.
